I have a data scraping company and I work with music services. Basically, we collect metadata from various accounts that we generate from different countries and reconstruct current trends, genres, tempo, top artists, authors, algorithms, etc., and we sell them B2B to our clients (major record labels) like UNIVERSAL, SONY, and WARNER. We currently have a problem with Spotify; they are "killing" the accounts, and we are forced each time to generate new ones, wasting unnecessary bandwidth. We have identified that the problem occurs when using the storage credentials (auth_blob) to request the access token (bearer), which lasts 1 hour, so we need to get it often. Then they, based on the quality of the IP, take them down (but we use residential proxies, even Oxylabs, because yes, we have Oxylabs unlocked for streaming services as enterprise clients). We are trying to understand if it’s a fingerprint issue or something else; it seems strange to me that the IPs from the providers are all dead.I have a lot of information about the RE of Spotify (mobile app) so I will definitely simplify the work. Are you able to solve the problem?

Interesting project, I will add a Mailchimp subscribe gate on your GoDaddy page via an embed section, with localStorage so subscribers skip it next visit, plus a short note on where to edit copy later. GoDaddy sandboxes custom JavaScript, so the reliable route is Mailchimp's hosted embed form paired with a localStorage unlock, not API calls. Questions: 1) Which Mailchimp audience should emails go into? 2) Should the unlock be per-device (localStorage) or time-limited (cookie)? Ready to start whenever you are. Faizan

Hello, After reviewing your project, I understand the issue around account instability and token lifecycle impacting your data pipeline. I’ve worked on large-scale data collection systems where reliability, rate control, and efficient session handling are critical, and I’m available to start right away. I bring strong experience in API Development, Cloud Computing, Data Processing, and Web Security with over 10 years of experience. In situations like this, the main challenge is not just access but maintaining a stable, efficient pipeline, so I would focus on analyzing your current flow, reducing unnecessary token requests, optimizing session reuse, and improving overall system resilience to avoid repeated overhead and data loss. I have a couple of quick questions. • Where in the flow do you see the highest failure rate—token generation, request stage, or data extraction? • Do you currently track session lifecycle metrics or failure patterns across accounts? Happy to go deeper on this and help stabilize your system. Best regards, Carlos

I can’t help troubleshoot or optimize account generation, fingerprinting, proxy usage, or token workflows in a way that’s meant to avoid Spotify’s detection systems or keep non-official accounts from being blocked. What I can say at a high level is this: what you’re describing (rapid account churn + automated token refresh + residential proxy rotation) is exactly the kind of pattern platforms like Spotify actively detect and degrade, and it’s rarely just one factor (IP quality or auth_blob alone). These systems usually combine multiple signals—authentication behavior, device/browser fingerprint consistency, request patterns, session reuse, and account graph behavior—so even “good” residential IPs won’t solve it if the identity/session model is unstable. If your business is selling trend intelligence to major labels, the sustainable path is to move away from account-based collection entirely and instead rely on: official Spotify Web API (with proper app registration and rate limits) licensed data providers (Chartmetric, SoundCharts, Luminate, etc.) partner/enterprise data access agreements where available If you want, I can help you redesign your pipeline into a compliant, stable architecture that still produces: genre/tempo clustering, artist trend detection, regional analytics, and cross-platform insights without account bans or infrastructure churn.

Hello there, I’m excited to help you turn this challenge into a robust, compliant data capability that your clients can rely on. Rather than focusing on bypassing protections or risky account lifecycles, I propose building an enterprise-grade data ingestion and analytics pipeline that leverages legitimate access points, licensing avenues, and hardened security practices to deliver stable metadata, trends, and audience insights for major labels. My approach includes: 1) API-driven data acquisition where possible (Spotify for Developers, official partner programs), 2) scalable data processing and enrichment on the cloud, with resilient token management and rate-limiting strategies, 3) a transparent fingerprinting and risk model to minimize account disruption, and 4) a security-first architecture (rotating credentials, IP reputation monitoring, and compliant proxy usage). The result will be a reliable, auditable flow that preserves bandwidth and reduces operational downtime while keeping you aligned with platform terms of service.

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have worked on similar projects involving reverse engineering of mobile apps and API security to sustain long-term automated access, making the process smoothly run without account bans. From my experience, the most critical factor is precisely identifying what triggers account suspensions, whether fingerprinting, IP reputation, or token renewal frequency. Approach: ⭕ Analyze your existing authentication flow and RE data for Spotify’s token generation and validation. ⭕ Investigate if fingerprinting or other request metadata is causing account bans beyond IP issues. ⭕ Develop a robust token refresh mechanism that mimics natural app behavior to avoid spikes. ⭕ Design and test with residential proxies, adapting logic dynamically to proxy quality and IP rotation. ⭕ Provide monitoring and alerting to preemptively catch suspicious triggers. ❓Could you please share the detailed RE data you have on Spotify’s auth system? ❓Are there any rate limits or behavior patterns already observed that correlate with account bans? I am confident I can develop a tailored antiban solution that will reduce your account turnover and bandwidth waste effectively. Looking forward to helping you solve this challenge. Best regards, Nam

Hi, Yes, I can work on this, and the problem you're describing makes sense to me technically. The fact that residential proxies from Oxylabs, with streaming unlocked,are still getting killed tells me the IP isn't the primary signal triggering the bans. Spotify's detection runs deeper than that. What they're most likely flagging is device fingerprint consistency. When you exchange the auth_blob for a bearer token, the request carries device-level signals, things like device ID, hardware model strings, OS build, app version, and network characteristics, that need to stay consistent across the lifetime of that account. If those values change between sessions or don't match the profile that was established at account creation, their backend flags it regardless of IP quality. The 1-hour bearer expiry forces you to re-authenticate frequently, which gives their system multiple chances to compare fingerprints and catch drift. My hypothesis is that either the device fingerprint isn't being persisted and replayed correctly between sessions, or some of the hardware/build values being spoofed are landing in ranges that Spotify's models have already flagged as synthetic. The auth_blob itself binding to a device fingerprint at creation is well-documented in their Android SDK, if that binding breaks at the token refresh step, it's game over for the account. With your RE notes on the mobile app this becomes much more tractable.

You need to stop high account churn caused by Spotify’s auth_blob -> bearer flow so you stop rebuilding accounts every week. Scope: diagnose whether bans come from IP signals, device/fingerprint mismatch, replayed auth_blob, or token refresh patterns; deliverable: a reproducible PoC that reliably requests tokens without triggering takedowns, plus integration scripts, per-account device state, and test metrics. Out of scope: creating accounts for you. Sharp insight: Spotify’s server checks are rarely triggered by IP alone — the failure mode is mismatched device/runtime telemetry during the auth_blob exchange (TLS/JA3, app signature, device IDs, clock skew, reuse patterns). Recreating the mobile client’s fingerprint and a per-account device state usually eliminates the heuristic that flags accounts. Proof: background in Android reverse engineering, web-security and API auth automation — this is the exact skillset needed to unpack auth_blob semantics and emulate the mobile handshake. Approach (short): reproduce the auth_blob->bearer flow in an instrumented environment (Frida/mitm), capture TLS/headers/device fields, implement per-account device-state + token refresh agent that mirrors mobile telemetry, integrate with your residential proxy pool, and run A/B ban-rate tests. Yes — able to diagnose and implement mitigations. Do you have recent network captures (auth_blob exchange) and one revoked account we can repro against, or should I start by instrumenting a clean mobile client in your environment?
